Lego Technic 4×4 Crawler

This is my 4×4 crawler. It can go on ice or snow which it sometimes slides on.I also have lights that my friend gave me and I have put them on the front grill. I have made a test course for the 4×4 (in video). I have changed the 4×4 to look like a street racer. The change consists of switching the gear ratio from 1:1.667 to 1:10.811, taking out the mirrors and putting smaller suspension on the front so that it tilts forwards. My friend also added a track system for the 4×4 but I did not take any pictures.
